Monetary Standards and Currency Systems

Currency-system terms for fiat money, legal tender, national currency, hard and soft currencies, gold standards, dollarization, and petrodollars.

This branch collects the monetary-system language behind currencies: fiat money, legal tender, national currency, hard and soft currencies, reserve or vehicle currencies, dollarization, gold standards, and petrodollar language.

These pages stay in Economics because the main question is how money systems and currency roles are organized, not how a trade is executed.
